How does zinc react to silver nitrate? What does it produce?

Jul 02, 2016·, studied Chemistry. Zinc is more electropositive than silver, when zinc is put into a solution of silver nitrate zinc reacts with the nitrate in the solution precipitating silver. 2Ag(NO3) + Zn → Zn(NO3)2 + 2Ag. Hope this helps:) Note: the metal is copper but the reaction is same as zinc.

Topic 3: Metals and Metal Extraction - Christine Kusznir

Silver (Ag) and gold (Au) need no extraction because they exist as elements in nature. Gold, because it is so unreactive, is found as the native metal and not as a compound. It does not need to be chemically extracted from its ore, but chemical reactions may be needed to remove other elements that might contaminate the metal.
